ADAU1361BCPZ-R7

ADAU1361 is a low power, stereo audio codec that supports stereo 48KHz record and playback at 14mW from a 1.8V analogue supply. The stereo audio ADCs and DACs support sample rates from 8KHz to 96KHz as well as a digital volume control. It is ideal for battery-powered audio and telephony applications. The record path includes an integrated microphone bias circuit and six inputs. The inputs can be mixed and mixed before the ADC, or they can be configured to bypass the ADC. It includes a stereo digital microphone input. It includes five high power output drivers (two differential and three single-ended), supporting stereo headphones, an earpiece, or other output transducer. AC-coupled or capless configurations are supported. Individual fine level controls are supported on all analogue outputs. It is used in applications such as smartphones/multimedia phones, digital still cameras/digital video cameras, portable media players/portable audio players, phone accessories products.
